The function g(x) = x3 has the point (-3, -27) on its graph. The function g(x) is even or odd
sashaice [31]

Answer:

The function g(x) is odd.

Step-by-step explanation:

Even and odd functions:

If for every value of x, f(x) = f(-x), the function is even.

If for every value of x, f(x) = -f(x), the function is odd.

If those statements are false, the function is neither even nor odd.

In this question:

g(x) = x^{3}

g(-x) = (-x)^{3} = -x^{3} = -g(x)

Since g(x) = -g(-x), the function g(x) is odd.

PLZ HELP ASAP RIGHT TRIANGLES

The correct answer is 45ft(along the ground)

Explanation:
It is making the right angled triangle as one half is 28 feet tall(vertically straight); the other half which fell over some distance is the hypotenuse. To find its length:

Hypotenuse = 81 - 28 = 53

Now that we have hypotenuse and the vertical length (perpendicular), we can find the base( along the ground) using Pythagoras theorem:

c^2 = a^2 + b^2

c = hypotenuse
a = perpendicular
b = base

53^2 = 28^2 + b^2
b = 45ft (along the ground)
